Title:
IMAGE DISPLY UNIT AND PRODUCTION METHOD FOR SPACER ASSEMBLY USED IN IMAGE DISPLAY UNIT
Document Type and Number:
WIPO Patent Application WO/2004/090930
Kind Code:
A1
Abstract:
An image display unit comprising a first substrate (10) having a fluorescent surface (16), a second substrate (12) disposed opposite to the first substrate across a space and provided with a plurality of electron emission sources (18) for exciting the fluorescent surface, and a spacer assembly (22) provided between the first and second substrates, for supporting an atmospheric pressure load acting on the substrates. The spacer assembly has platy grids (24) and spacers (30a, 30b) erected on the grids. The spacers have their volume resistances gradually reduced respectively from the grid side toward the substrate sides. The above construction can prevent an electron beam from deviatiang from a trajectory, reduce a deterioration in color purity, and ensure a discharge withstand voltage between the first and second substrates to keep an anode voltage at a high level and improvae the luminance of a display image.
